Vertical star-shape high-pressure air compressor

Abstract

The invention discloses a vertical star-shape high-pressure air compressor. The air compressor is high in gas compression rate, stable in machine working, small in noise, low in failure rate, small in integral machine size, compact in arrangement, and convenient to repair and inspect. The air compressor comprises a vertically arranged motor, a crank shaft case, a first-stage cylinder, a second-stage cylinder, a third-stage cylinder a fourth-stage cylinder, a first-stage cooler, a second-stage cooler, a third-stage cooler and a fourth-stage cooler, wherein a crank shaft is connected with a main shaft of the motor; the first-stage cylinder, the second-stage cylinder, the third-stage cylinder and the fourth-stage cylinder are arranged in a radial star shape along the radial direction of the main shaft of the motor; four vibration isolators which are connected under the crank shaft case through a bracket; the first-stage cooler is arranged under the first-stage cylinder, the second-stage cooler and a second-stage oil-water separator are combined into a whole and are arranged above the third-stage cylinder; two ends of the third-stage cooler and the fourth-stage cooler and a third-stage oil-water separator and a fourth-stage oil-water separator are combined into whole and are arranged above the second-stage cylinder; an oil holding disc is arranged above the crank shaft case; the cylinders are connected through pipelines; two ends of the crank shaft are connected with an upper balance weight and a lower balance weight; an oil groove is formed in the lower end surface of each connecting rod.

Description

technical field [0001] The invention relates to an air compressor, in particular to a high-pressure air compressor. Background technique [0002] High-pressure air compressors have been widely used in many industries of the national economy. Traditional piston air compressors are mostly horizontal V-shaped or W-shaped arrangements, which are bulky, inconvenient to maintain, have many valves, many fault points, and complex pipelines. Large vibration and high noise. Contents of the invention [0003] The technical problem solved by the present invention is to provide a vertical star-shaped high-pressure air compressor, which has a high gas compression ratio, stable operation, low noise, low failure rate, small overall volume, compact arrangement, and is convenient for maintenance and inspection. [0004] In order to achieve the above object, the vertical star-type high-pressure air compressor of the present invention includes a vertically arranged motor, and also includes ...
